I needed a couple of books to take on my hols to France (depressing weather, so much for a suntan!) and I took, among others, AFTER and I KNOW IT'S OVER.
AFTER: I really liked it - i know it's had 'meh' reviews, but I really liked Tom and his friends, and it was creepy how something like that could happen to your school before you realise.
I KN0W IT'S 0VER: I didn't really like this one much. Nick, the MMC, was a really interesting character, and his relationships with girls, family and friends, plus his reaction to the massive news that Sasha (his ex-gf) was pregnant made him so real. I didn't like Sasha though, and the ending was a bit dissappointing.
